commit 233709d2cd6bbaaeda0aeb8d11f6ca7f98563b39 upstream. This can be the case when the GPU is powered off, e.g. via vgaswitcheroo or runpm. When the GPU is powered up again, radeon_gart_table_vram_pin flushes the TLB after setting rdev->gart.ptr to non-NULL. Fixes panic on powering off R7xx GPUs.

commit 2ba8d1bb8f6b589037f7db1f01144fc80750e8f7 upstream.

2015-08-03drm/radeon: compute ring fix hibernation (CI GPU family) v2.Jérôme Glisse1-0/+34
commit 161569deaa03cf3c00ed63352006193f250b0648 upstream. In order for hibernation to reliably work we need to cleanup more thoroughly the compute ring. Hibernation is different from suspend resume as when we resume from hibernation the hardware is first fully initialize by regular kernel then freeze callback happens (which correspond to a suspend inside the radeon kernel driver) and turn off each of the block. It turns out we were not cleanly shutting down the compute ring. This patch fix that. Hibernation and suspend to ram were tested (several times) on : Bonaire Hawaii Mullins Kaveri Kabini Changed since v1: - Factor the ring stop logic into a function taking ring as arg.

commit 6dfd197283bffc23a2b046a7f065588de7e1fc1e upstream. Laptop with Turks/Thames GPU will freeze if dpm is enabled. It seems the SMC engine is relying on some state inside the CP engine.

2015-06-23drm/i915: Fix DDC probe for passive adaptersJani Nikula1-3/+17
commit 3f5f1554ee715639e78d9be87623ee82772537e0 upstream. Passive DP->DVI/HDMI dongles on DP++ ports show up to the system as HDMI devices, as they do not have a sink device in them to respond to any AUX traffic. When probing these dongles over the DDC, sometimes they will NAK the first attempt even though the transaction is valid and they support the DDC protocol. The retry loop inside of drm_do_probe_ddc_edid() would normally catch this case and try the transaction again, resulting in success. That, however, was thwarted by the fix for [1]: commit 9292f37e1f5c79400254dca46f83313488093825 Author: Eugeni Dodonov <eugeni.dodonov@intel.com> Date: Thu Jan 5 09:34:28 2012 -0200 drm: give up on edid retries when i2c bus is not responding This added code to exit immediately if the return code from the i2c_transfer function was -ENXIO in order to reduce the amount of time spent in waiting for unresponsive or disconnected devices. That was possible because the underlying i2c bit banging algorithm had retries of its own (which, of course, were part of the reason for the bug the commit fixes). Since its introduction in commit f899fc64cda8569d0529452aafc0da31c042df2e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links we've been flipping back and forth enabling the GMBUS transfers, but we've settled since then. The GMBUS implementation does not do any retries, however, bailing out of the drm_do_probe_ddc_edid() retry loop on first encounter of -ENXIO. This, combined with Eugeni's commit, broke the retry on -ENXIO. Retry GMBUS once on -ENXIO on first message to mitigate the issues with passive adapters. This patch is based on the work, and commit message, by Todd Previte <tprevite@gmail.com>.

commit e058c945e03a629c99606452a6931f632dd28903 upstream. According to the HSW b-spec we need to try clock divisors of 63 and 72, each 3 or more times, when attempting DP AUX channel communication on a server chipset. This actually wasn't happening due to a short-circuit that only checked the DP_AUX_CH_CTL_DONE bit in status rather than checking that the operation was done and that DP_AUX_CH_CTL_TIME_OUT_ERROR was not set.

2015-05-17drm/i915: Add missing MacBook Pro models with dual channel LVDSLukas Wunner1-1/+17
commit 3916e3fd81021fb795bfbdb17f375b6b3685bced upstream. Single channel LVDS maxes out at 112 MHz. The 15" pre-retina models shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz) as a BTO option, both versions used dual channel LVDS even though the smaller one would have fit into a single channel. Notes: Bug report showing that the MacBookPro8,2 with 1440x900 uses dual channel LVDS (this lead to it being hardcoded in intel_lvds.c by Daniel Vetter with commit 618563e3945b9d0864154bab3c607865b557cecc): https://bugzilla.kernel.org/show_bug.cgi?id=42842 If i915.lvds_channel_mode=2 is missing even though the machine needs it, every other vertical line is white and consequently, only the left half of the screen is visible (verified by myself on a MacBookPro9,1). Forum posting concerning a MacBookPro6,2 with 1440x900, author is using i915.lvds_channel_mode=2 on the kernel command line, proving that the machine uses dual channels: https://bbs.archlinux.org/viewtopic.php?id=185770 Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all MacBook Pro "A1286" models, and that model number encompasses the MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's driven with dual channel LVDS: http://www.ebay.com/itm/-/400690878560 http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286 http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones with i915 graphics and dual channel LVDS, so that list should be complete. And the 8,2 is already in intel_lvds.c. Possible motivation to use dual channel LVDS even on the 1440x900 models: Reduce the number of different parts, i.e. use identical logic boards and display cabling on both versions and the only differing component is the panel.

commit 9535c4757b881e06fae72a857485ad57c422b8d2 upstream. The hardware, according to the specs, is limited to 256 byte transfers, and current driver has no protections in case users attempt to do larger transfers. The code will just stomp over status register and mayhem ensues. Let's split larger transfers into digestable chunks.

2015-02-06drm/i915: Only fence tiled region of object.Bob Paauwe1-0/+7
commit af1a7301c7cf8912dca03065d448c4437c5c239f upstream. When creating a fence for a tiled object, only fence the area that makes up the actual tiles. The object may be larger than the tiled area and if we allow those extra addresses to be fenced, they'll get converted to addresses beyond where the object is mapped. This opens up the possiblity of writes beyond the end of object. To prevent this, we adjust the size of the fence to only encompass the area that makes up the actual tiles. The extra space is considered un-tiled and now behaves as if it was a linear object.

2015-01-30drm/i915: Fix mutex->owner inspection race under DEBUG_MUTEXESChris Wilson1-1/+1
commit 226e5ae9e5f9108beb0bde4ac69f68fe6210fed9 upstream. If CONFIG_DEBUG_MUTEXES is set, the mutex->owner field is only cleared if the mutex debugging is enabled which introduces a race in our mutex_is_locked_by() - i.e. we may inspect the old owner value before it is acquired by the new task. This is the root cause of this error: # diff --git a/kernel/locking/mutex-debug.c b/kernel/locking/mutex-debug.c # index 5cf6731..3ef3736 100644 # --- a/kernel/locking/mutex-debug.c # +++ b/kernel/locking/mutex-debug.c # @@ -80,13 +80,13 @@ void debug_mutex_unlock(struct mutex *lock) # DEBUG_LOCKS_WARN_ON(lock->owner != current); # # DEBUG_LOCKS_WARN_ON(!lock->wait_list.prev && !lock->wait_list.next); # - mutex_clear_owner(lock); # } # # /* # * __mutex_slowpath_needs_to_unlock() is explicitly 0 for debug # * mutexes so that we can do it here after we've verified state. # */ # + mutex_clear_owner(lock); # atomic_set(&lock->count, 1); # } Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=87955 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit add284a3a2481e759d6bec35f6444c32c8ddc383 upstream. In order to act as a full command barrier by itself, we need to tell the pipecontrol to actually stall the command streamer while the flush runs. We require the full command barrier before operations like MI_SET_CONTEXT, which currently rely on a prior invalidate flush.

commit 2b387059817fd100cddc5a97118d63e3f3fade74 upstream. In all likelihood we will do a few hundred errnoneous register operations if we do a single invalid register access whilst the device is suspended. As each instance causes a WARN, this floods the system logs and can make the system unresponsive.
